Argument	Type	Description
`token`Required	token	Authentication token bearing required scopes. Tokens should be passed as an HTTP Authorization header or alternatively, as a POST parameter. Example`xxxx-xxxxxxxxx-xxxx`
`cursor`	string	Paginate through collections of data by setting the `cursor` parameter to a `next_cursor` attribute returned by a previous request's `response_metadata`. Default value fetches the first "page" of the collection. See pagination for more detail. Example`dXNlcjpVMDYxTkZUVDI=`
`include_locale`	boolean	Set this to `true` to receive the locale for users. Defaults to `false` Example`true`
`limit`	integer	The maximum number of items to return. Fewer than the requested number of items may be returned, even if the end of the users list hasn't been reached. Providing no `limit` value will result in Slack attempting to deliver you the entire result set. If the collection is too large you may experience `limit_required` or HTTP 500 errors. Default: `0` Example`20`
`team_id`	team	encoded team id to list users in, required if org token is used Example`T1234567890`

Present arguments as parameters in application/x-www-form-urlencoded querystring or POST body. This method does not currently accept application/json.

Common error response

Typical error response

{
    "ok": false,
    "error": "invalid_cursor"
}

This method returns a list of all users in the workspace. This includes deleted/deactivated users.

Returns a list of paginated user objects, in no particular order.

Profile

The profile hash contains as much information as the user has supplied in the default profile fields: first_name, last_name, real_name, email, skype, and the image_* fields. Data that has not been supplied may not be present at all, may be null or may contain an empty string ("").

A user's custom profile fields may be discovered using users.profile.get.

Email addresses

Accessing email addresses
The users:read.email OAuth scope is now required to access the email field in user objects returned by the users.list and users.info web API methods. users:read is no longer a sufficient scope for this data field. Learn more.

Apps created after January 4th, 2017 must request both the users:read and users:read.email OAuth permission scopes when using the OAuth app installation flow to enable access to the email field of user objects returned by this method.

Pagination

This method uses cursor-based pagination to make it easier to incrementally collect information. To begin pagination, specify a limit value under 1000. We recommend no more than 200 results at a time.

Responses will include a top-level response_metadata attribute containing a next_cursor value. By using this value as a cursor parameter in a subsequent request, along with limit, you may navigate through the collection page by virtual page.

See pagination for more information.

Presence

Retrieving a workspace's presence with this method is now deprecated. Use users.getPresence or presence subscriptions instead.

Errors

This table lists the expected errors that this method could return. However, other errors can be returned in the case where the service is down or other unexpected factors affect processing. Callers should always check the value of the ok params in the response.

Error	Description
`invalid_cursor`	Value passed for `cursor` was not valid or is no longer valid.
`limit_required`	For large teams a limit is required.
`missing_argument`	A required argument is missing.
`team_access_not_granted`	The token used is not granted the specific workspace access required to complete this request.
`user_removed_from_team` [hidden]	user removed from team (generated)
`not_authed`	No authentication token provided.
`invalid_auth`	Some aspect of authentication cannot be validated. Either the provided token is invalid or the request originates from an IP address disallowed from making the request.
`account_inactive`	Authentication token is for a deleted user or workspace when using a `bot` token.
`token_revoked`	Authentication token is for a deleted user or workspace or the app has been removed when using a `user` token.
`no_permission`	The workspace token used in this request does not have the permissions necessary to complete the request. Make sure your app is a member of the conversation it's attempting to post a message to.
`org_login_required`	The workspace is undergoing an enterprise migration and will not be available until migration is complete.
`ekm_access_denied`	Administrators have suspended the ability to post a message.

`two_factor_setup_required`	Two factor setup is required.
`enterprise_is_restricted`	The method cannot be called from an Enterprise.

`invalid_arg_name`	The method was passed an argument whose name falls outside the bounds of accepted or expected values. This includes very long names and names with non-alphanumeric characters other than `_`. If you get this error, it is typically an indication that you have made a very malformed API call.
`invalid_array_arg`	The method was passed an array as an argument. Please only input valid strings.
`invalid_charset`	The method was called via a `POST` request, but the `charset` specified in the `Content-Type` header was invalid. Valid charset names are: `utf-8` `iso-8859-1`.
`invalid_form_data`	The method was called via a `POST` request with `Content-Type` `application/x-www-form-urlencoded` or `multipart/form-data`, but the form data was either missing or syntactically invalid.
`invalid_post_type`	The method was called via a `POST` request, but the specified `Content-Type` was invalid. Valid types are: `application/json` `application/x-www-form-urlencoded` `multipart/form-data` `text/plain`.
`missing_post_type`	The method was called via a `POST` request and included a data payload, but the request did not include a `Content-Type` header.
`team_added_to_org`	The workspace associated with your request is currently undergoing migration to an Enterprise Organization. Web API and other platform operations will be intermittently unavailable until the transition is complete.
`invalid_json` [hidden]	The method was called via a `POST` request with `Content-Type` `application/json`, but the body was not valid JSON.
`json_not_object` [hidden]	The method was called via a `POST` request a valid JSON body, but the JSON value was not an object.
`ratelimited`	The request has been ratelimited. Refer to the `Retry-After` header for when to retry the request.
`accesslimited`	Access to this method is limited on the current network
`request_timeout`	The method was called via a `POST` request, but the `POST` data was either missing or truncated.
`upgrade_required` [hidden]	The calling application needs to be upgraded.
`service_unavailable`	The service is temporarily unavailable
`fatal_error`	The server could not complete your operation(s) without encountering a catastrophic error. It's possible some aspect of the operation succeeded before the error was raised.
`internal_error`	The server could not complete your operation(s) without encountering an error, likely due to a transient issue on our end. It's possible some aspect of the operation succeeded before the error was raised.

Warnings

This table lists the expected warnings that this method will return. However, other warnings can be returned in the case where the service is experiencing unexpected trouble.

Warning	Description
`missing_charset`	The method was called via a `POST` request, and recommended practice for the specified `Content-Type` is to include a `charset` parameter. However, no `charset` was present. Specifically, non-form-data content types (e.g. `text/plain`) are the ones for which `charset` is recommended.
`superfluous_charset`	The method was called via a `POST` request, and the specified `Content-Type` is not defined to understand the `charset` parameter. However, `charset` was in fact present. Specifically, form-data content types (e.g. `multipart/form-data`) are the ones for which `charset` is superfluous.
